Programme implementation in social and emotional learning: basic issues and research findings.

This paper discusses the fundamental importance of achieving quality implementation when assessing the impact of social and emotional learning interventions. Recent findings in implementation science are reviewed that include a definition of implementation, its relation to programme outcomes, current research on the factors that affect implementation, and a framework for understanding the steps, actions and challenges involved in achieving quality implementation. Examples from the social and emotional learning literature are used to illustrate different issues. [ABSTRACT FROM AUTHOR]
